<p><i>declared in "ogg/ogg.h";</i></p>

|
|
|
||
|
|
<p>This function forms packets into pages.</p>
|
||
|
|
|
||
|
|
<p>In a typical encoding situation, this would be called after using <a
|
||
|
|
href="ogg_stream_packetin.html">ogg_stream_packetin()</a> to submit
|
||
|
|
data packets to the bitstream. Internally, this function assembles
|
||
|
|
the accumulated packet bodies into an Ogg page suitable for writing
|
||
|
|
to a stream. The function is typically called in a loop until there
|
||
|
|
are no more pages ready for output.</p>
|
||
|
|
|
||
|
|
<p>This function will only return a page when a "reasonable" amount of
|
||
|
|
packet data is available. Normally this is appropriate since it
|
||
|
|
limits the overhead of the Ogg page headers in the bitstream, and so
|
||
|
|
calling ogg_stream_pageout() after ogg_stream_packetin() should be the
|
||
|
|
common case. Call <a href="ogg_stream_flush.html">ogg_stream_flush()</a>
|
||
|
|
if immediate page generation is desired. This may be occasionally
|
||
|
|
necessary, for example, to limit the temporal latency of a variable
|
||
|
|
bitrate stream.</p>

<h3>Parameters</h3>
|
||
|
|
<dl>
|
||
|
|
<dt><i>os</i></dt>
|
||
|
|
<dd>Pointer to a previously declared <a href="ogg_stream.html">ogg_stream</a> struct, which represents the current logical bitstream.</dd>
|
||
|
|
<dt><i>og</i></dt>
|
||
|
|
<dd>Pointer to an <a href="ogg_page.html">ogg_page</a> structure to fill
|
||
|
|
in. Data pointed to is owned by libogg. The structure is valid until the
|
||
|
|
next call to ogg_stream_pageout(), ogg_stream_packetin(), or
|
||
|
|
ogg_stream_flush().</dd>

|

|

|
|
<h3>Return Values</h3>
|
||
|
|
<blockquote>
|
||
|
|
<li>Zero means that insufficient data has accumulated to fill a page, or an internal error occurred. In
|
||
|
|
this case <i>og</i> is not modified.</li>
|
||
|
|
<li>Non-zero means that a page has been completed and returned.</li>
|
||
